Hi Eric

Fitted and sorted, both coils intact I get around 9v on the relay coil but operates this is due to me turning down the rheostat,,,,and as expected on the other coil.

Once again thanks for the help. BTW. your box of goodies keep on helping me out,, cheers

Regards

Have a question about Relays:
I have seen that relays with Low resistance draw more current,
and relays with high resistance draw less current;
If the source voltage cannot provide a sufficient(big) current, all of us incline to use a High resistance relay, because it draws low current.
If high resistance relays draw less current then why cant we use it for all applications? Why do we require Low resistance relays?

If i have a 5V (1A) Source, i can use any of these relays;
